   供应商选择器（带图标）—— 2026-09-17
   老板 BUG：「供应商列表 没有对应的 AI 供应商的图标」。
   原生 <select> 的 option **无法**放图标，所以它退居「值源」被视觉隐藏，
   真正给用户看的是 #cfgBrandBtn（当前项）+ #cfgBrandPanel（图标列表）。
   绑定链一个字没动：选中后写 select.value 再派发 change，bindModelSettings /
   el.onchange / saveModel / 探针的 cfg_brand 判据全部照旧。

   ⚠️ 这几条规则**故意不带 `#page-ai` 前缀**：弹窗会被 portal 到
   `document.body`（为了在 AI 模型库页面也能弹），带前缀就套不上了。

   ★★ 效果反馈页 · 窄屏版式（老板 2026-09-19 本轮 §五）★★
   ----------------------------------------------------------------
   老板原话：「修复反馈页窄屏布局。**收起不必要的对话栏**；
             素材列表与详情**支持切换**。在 1440、1180、960px 下截图验收，
             不只检查元素是否重叠。」

   两个毛病：
     ① 左侧 260px「会话列表」和反馈流程毫无关系，窄屏下白占四分之一宽度；
     ② 素材资产（4 栏）与优化实验（8 栏）并排，960px 下两块都装不下自己的表单
        —— 实测左右栏都出现容器级横向溢出（表单/按钮被裁掉，点不到）。

   修法（**宽屏一字不动**，只在 ≤1180px 生效）：
     · 会话栏 → 默认收起，右上「会话栏」按钮可展开（展开时以浮层覆盖，不挤压内容）；
     · 4/8 并排 → 单栏 + 切换条，一次只显示一块。
   ⚠ DOM 类名（grid-cols-12 / col-span-4 / col-span-8 / ai-split）**一个都没改**，
     这里只新增轨道与显隐规则 —— 与设计稿的对应关系保持不变。
